The condom may be the worlds oldest gadget, but it continues to evolve. The recent development of the snap-on Pronto condom in South Africa has saved countless lives, after it was found that easy to open packaging had a huge effect on usage by not destroying the moment.

We have chosen a dozen different commercials from a dozen different countries, many of which show different cultural attitudes and fantastically oblique humor.

Contrary to the headlines on YouTube and blogs, these commercials are not banned, however most could not be shown on national TV in the US, which has some of the world's strictest, self-imposed, censorship. The fact that they could be shown on cable suggests that this is not necessarily a cultural issue, but rather a result of a vocal, prudish minority. McCann Erickson's Million Sperm film, for example, is listed as banned but actually won several awards after being broadcast.
